LEFT ATRIAL APPENDAGE TREATMENT SYSTEMS AND METHODS

摘要

Embodiments of the present invention encompass systems and methods to prevent complications from atrial fibrillation by preventing or reducing the likelihood of blood flow out of the left atrial appendage, to eliminate a possible source of aberrant electrical circuits, or both. Accordingly, techniques are provided for delivering ligature loops or closure means to the left atrial appendage, and to other anatomical structures of a patient which may be desirable in other surgical procedures.

主权项

1. A ligature delivery system for use with an anatomical structure closure mechanism, the ligature delivery system comprising:
a delivery mechanism comprising a cinchable loop that engages the closure mechanism and that rotates axially about a central longitudinal axis between a first configuration whereby the closure mechanism is shielded from the anatomical structure of a patient and a second configuration whereby the closure mechanism can be released onto the anatomical structure; and a delivery control mechanism that cinches the cinchable loop about the anatomical structure and that switches the cinchable loop between the first and second configurations.
